What to do instead
- Your printer's bed maxes out at 0°C, but PC needs at least 100°C for reliable adhesion.
- Try a compatible filament for your Markforged Onyx Pro — PLA, PETG, and ABS are good options.
- If you need PC specifically, you'll need a printer with a hotend capable of 260°C+ nozzle and 100°C+ heated bed.
